Explanatory Notes on the Whole Bible, by John Wesley, [1754-65], at sacred-texts.com
lev 17:3That killeth - Not for common use, for such beasts might be killed by any person or in any place but for sacrifice. In the camp, or out of the camp - That is, anywhere.
lev 17:4The tabernacle - This was appointed in opposition to the Heathens, who sacrificed in all places; to cut off occasions of idolatry; to prevent the people's usurpation of the priest's office, and to signify that God would accept of no sacrifices but through Christ and in the Church; (of both which the tabernacle was a type.) But though men were tied to this law, God was free to dispense with his own law, which he did sometimes to the prophets, as Sa1 7:9, Sa1 11:15. He hath shed blood - He shall be punished as a murderer. The reason is, because he shed that blood, which, though not man's blood, yet was precious, being sacred and appropriated to God, and typically the price by which men's lives were ransomed.
lev 17:5They offer - The Israelites, before the building of the tabernacle, did so, from which they are now restrained. Peace - offerings - He nameth not these exclusively from others, as appears from the reason of the law, and from Lev 17:8-9, but because in these the temptation was more common in regard of their frequency, and more powerful, because part of these belonged to the offerer, and the pretence was more plausible, because their sanctity was of a lower degree than others, these being only called holy, and allowed in part to the people, whereas the others are called most holy, and were wholly appropriated either to God, or to the priests.
lev 17:6Upon the altar - This verse contains a reason of the foregoing law, because of God's propriety in the blood and fat, wherewith also God was well pleased, and the people reconciled. And these two parts only are mentioned, as the most eminent, and peculiar, though other parts also were reserved for God.
lev 17:7Unto devils - So they did, not directly or intentionally, but by construction and consequence, because the devil is the author of idolatry, and is eminently served, and honoured by it. And as the Egyptians were notorious for their idolatry, so the Israelites were infected with their leaven, Jos 24:14, Eze 20:7, Eze 23:2-3. A whoring - Idolatry, especially in God's people, is commonly called whoredom, because it is a violation of that covenant by which they were peculiarly betrothed or married to God.
lev 17:10I will set my face - I will be an enemy to him, and execute vengeance upon him immediately; because such persons probably would do this in private, so that the magistrate could not know nor punish it. Write that man undone, for ever undone, against whom God sets his face.
lev 17:11Is in the blood - Depends upon the blood, is preserved and nourished by it. The blood maketh atonement - Typically, and in respect of the blood of Christ which it represented, by which the atonement is really made. So the reason is double; because this was eating up the ransom of their own lives, which in construction was the destroying of themselves. because it was ingratitude and irreverence towards that sacred blood of Christ which they ought to have in continual veneration.
lev 17:15That eateth - Through ignorance or inadvertency; for if it was done knowingly, it was more severely punished. A stranger - Who is a proselyte to the Jewish religion: other strangers were allowed to eat such things, Deu 14:21, out of which the blood was either not drawn at all, or not regularly.
lev 17:16His iniquity - The punishment of it, and therefore must offer a sacrifice for it.
